RADIATOR.

Specification of Letters Patent.

Patented aan. i3, 1920.

Application filed January 25, 1918. Serial No. 213,699.

' Radiators, of which the following is a specip fication.

My invention relates to radiators for cooling internal combustion engines for use on automobiles and other high speed vehicles.

The object ofthe invention is to so form the radiator grilles or tubes as the case may be that they will offer the least possible resistance to the air. A

In the accompanying drawings in which like reference numerals refer to corresponding parts:

Figure 1 is a front elevation o f a radiator illustrating the preferred embodiment of my invention;

Fig. 2 is a horizontal transverse section of the same. l

Referring more particularly to the drawings, the radiator R which I have shown to illustrate the preferred form of my invention. comprises, the filling compartment 1' having the inlet or filling opening 2; A series of radiator sections or grilles 3 communicate with the filling compartmentl inany well known manner, not shown, to provide for a circulation of water through the chambers or hollow portions 4. As best seen in Fig. 1 the chambers 4 of one row of grilles are preferably staggered with respect to similar portions in the next adj acent row.

As the invention relates to the shape) of A the water chambers 4 further descriptlon of the general construction of the radiator is 40 deemed unnecessary.

It will be noted that the chambers 4 are substantially pear shaped, in horizontal cross section and tapered from front to'rear thus presenting a smooth streamline outer surface along which the air may flo-W without being broken up into eddies or currents and causing excess resistance. Where great speed is essential the elementv of resistance is a factor to be seriously considered as will vbe readily understood. This applicant has proven by Careful tests, that by forming the grid of the radiator on the streamline principles just described not only greater speed can be attained but also a better cooling'action of the liquid flowing through .the radiator will result. The greater cooling effect thus obtained is due to the fact that the air instead of breaking off into eddies will closely hug the streamline surface of the chambers 4 in the manner illustrated in Fig. 2.

Having thus described my invention, what I claim is:

A radiator for automobiles and the like comprising a plurality of tubes having spaced communicating alined Water' chambers of substantial pear` shape in horizontal section land tapered from front to rear, the chambers of one tube being staggered with A.respect to the chambers of the adjacent tubes.

In testimony whereof ture in presence of two Witnesses.
